Racecapture App by Autosport Labs. It's streaming data via wifi from the Racecapture Pro MK3 unit that is connected to the ECU via CAN and I have seven external analog sensors input as well.

Did some more fine tuning today.
Decided to try out 29psi out the top. I think I started to reach the limit of my current fuel system. It's dropping 4-5psi of fuel pressure now and leaning out about .5 AFR in the process.
You can see it in the log here: https://datazap.me/u/razorlab/2nd-4t...&zoom=885-1802
Don't pay attention to the weird log drop outs, working through some logger workings.
I guess I'll install my Radium -8AN feed line and larger fuel filter now...
The car is making great power now. It feels much faster than the 600whp chart I posted before, most likely because it's filling in the curve more and running more torque.

Okay, I'm done with the high boost mapping of the car. It's dropping fuel pressure anyway. I added more timing up top and held the boost a bit more and this is what it gave me.
Pretty darn pleased with that for a PT5858 .82

And here was the road getting here:

Now I swear I will really do the track tune.

Pulled the old laptop out of the closet in search of some old logs and found some from way back when.
These are fun...
Now vs when the car was 100% stock, no tune, 91oct:

Now vs 100% stock vs Bolt ons and E85:

HOLY CRAP!
Looks fantastic. For a while there you were being crushed by the gremlins. Now your on the other side of the lunacy that can happen with heavy mods and this look great!
I really like the 200 ft-lbs at 3400 rpm. Not bad at all. Not bad...

Installed the new Torqbyte CM5-LT + PM3 fuel controller setup.
Made a custom mounting plate for the PM3 fuel pump controller unit. Was a quick thing I threw together. Will eventually paint it black but wanted to make sure it mounted up correctly first. The Mitsu keyless module is to the left of the PM3. I used it's mounting for this so I figured I would mount it in the same place.
I have to also clean up the wiring and figure out where to put the CM5-LT unit as well. Probably behind the battery.
I also did another compression test. New engine now has 1,200 miles.
Cyl 1 - 168
Cyl 2 - 170
Cyl 3 - 168
Cyl 4 - 169

Small update.
finished installing the fuel pump controller units. Cleaned up the wiring and added inline fuses for both units. I am going to redo the top plate as I can't put back on the plastic trunk barrier with the unit mounted there. Hopefully be an easy change. Really happy with this new unit.
Also started my track tune. I want to track the car with around E45-E55 so I don't have to bring a ton of fuel to the track.
With E53, 24.5psi and AFR's way too rich (11.0 to 10.7) it's making 540whp so I think I might end up running even lower boost as the car is still crazy fast and if I can track with lower boost and it still make 500whp I'll be a happy camper.
More to come.
